As Bethenny Frankel focuses on healing
after filing for divorce
from husband Jason Hoppy, she seems to have a very special supporter by her side: hedge fund mogul Warren Lichtenstein, who's reportedly been helping her move past her split.
But is she moving on with Lichtenstein, the chairman and CEO of Steel Partners Holdings L.P.?
"Bethenny and Warren have been great friends for more than 20 years, and he has really been a support system during this sad time," a source tells the U.K.'s Daily Mail
The source also quelled rumors that the reality star, 42, moved into his $6.3 million Upper East Side, N.Y., apartment. However, she did clock in some time at his Manhattan digs – when he wasn't home.
She reportedly stayed at the billionaire's place for one night with 2-year-old daughter Bryn "so that she and Bryn could have some girl time," adds the source. Hoppy, whom she married in 2010
, still lives in the former couple's Tribeca loft, according to the Daily Mail
It's been just less than a month since Frankel announced her split
from Hoppy. "I feel like a failure," she recently told Ellen DeGeneres
. "I really put it out there. I wanted the fairy tale."
